Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the lens assembly is miniaturized to reduce size, then the device becomes more compact, but the reliability and durability of the auto focus and optical image stabilization functions deteriorate
Solution Approach 1:
The patent employs flexible connection members made of elastic non-conductive material that can accommodate movement in both optical axis direction (auto focus) and perpendicular directions (optical image stabilization) without breaking. These flexible connection members replace rigid structures, allowing the compact lens assembly to maintain structural integrity during multi-directional movements, thus resolving the contradiction between miniaturization and functional durability.
Solution Approach 2:
The patent uses composite material structures combining elastic non-conductive materials for connection members with conductive elements for drivers and sensors. This composite approach allows the lens assembly to achieve both compact size and reliable operation by optimizing each component's material properties for its specific function while maintaining overall small form factor.
2Ease of manufacture
If connection members are made rigid for structural stability, then manufacturing is easier, but the ability to accommodate multi-directional movement is reduced
Solution Approach 1:
The connection members are designed with flexible elastic non-conductive material that can bend and deform to accommodate movements in both the optical axis direction and perpendicular directions. This flexibility allows a single connection member structure to handle multiple movement directions, eliminating the need for separate rigid structures for each direction while maintaining ease of manufacture through injection molding.
Solution Approach 2:
The connection members are designed as dynamic, flexible components rather than static rigid structures. They can adapt their shape and stiffness characteristics during operation to accommodate different movement directions, providing both ease of manufacture and versatile movement accommodation capability simultaneously.
